| In order to improve the quality of classroom teaching,some scholars in developed countries began to study classroom teaching mode,which provided theoretical guidance for teachers to complete teaching tasks and effective learning.It is one of the effective ways to carry out the curriculum teaching practice and apply the cognitive theory to the whole process of teaching through the distinction of class type and then the construction of different teaching modes.Curriculum content determines teaching form,classroom teaching can not be carried out in a fixed mode.We should classify classes according to different curriculum nature,objectives,contents,organization or way,and design different teaching modes combined with disciplinary characteristics and class structure.According to the survey found that some of the classroom teaching,primary school mathematics classroom teaching design is random,the form of classroom teaching and program design of some confusion,lack of knowledge,the nature of curriculum objectives,content,organization or mode of the design and implementation of classroom teaching,the process and methods of some class of bilateral activities of the organization is difficult to control,which leads to the effect of classroom teaching can not guarantee the phenomenon.Therefore,this paper will carry out the study of the sub class of mathematics curriculum for this situation,and provide some reference for the choice of the classroom teaching mode and the teaching design.It will become a hot issue in the field of teaching and research to differentiate class type and construct classroom teaching mode so as to diversify and individualize the design of teachers’ teaching.Through the research,we can see that the primary school mathematics teaching mode is more flexible,which can regulate classroom teaching behavior,avoid randomness,and improve students’ mathematical thinking quality.First,through literature analysis,individual interviews,classroom observation and other research methods,we know the design and implementation of primary school mathematics teaching and evaluation criteria,provide classification criteria and methods for class classification,and find out relatively reasonable research ideas.Secondly,based on carefully review the relevant theory books of mathematics teaching design and classroom teaching evaluation index system,classification standard,classification type of lessons by experts and teachers interview in-depth understanding,to correctly understand and grasp all kinds of course connotation and denotation and related facts.At the same time,we have consulted the origin,development history,measurement and measurement methods,measurement units and norms of the concept of area,in-depth analyzed the teaching content and teaching objectives and the selection basis of teaching mode,and laid a theoretical foundation for the subsequent research of classroom teaching design.Third,based on a large number of classroom teaching designs or related literature,we investigated and analyzed the current situation of primary mathematics classes through questionnaires,expert interviews and classroom observation.Fourth,based on the theoretical research and support classes of several primary school mathematics courses based on the actual survey,focusing on the concept of class,class,exercise class and the lesson lesson design,teaching content for quadrilateral area calculation.These cases according to different contents,choose different teaching modes.Through these lesson study,provides some visual material for teaching,to make some modest for primary school mathematics classroom reform in our school.The targeted design classroom teaching can play a positive role in the current mathematics classroom,and students learn more purposeful.The cognitive level and the teaching design should follow the students,according to the different levels of students,teaching for different ways,such as the concept of teaching to emphasize teachers can guide students to communicate with each other between students,like the polygon area calculation of this type of course,let the students hands-on,fully mobilize students’ learning initiative.Therefore,class teaching can effectively improve the quality of teaching and exercise students’ mathematical thinking. |
